From 5de2fc3ff2ba2cbbfb5d0d4f3c6ba032469feae5 Mon Sep 17 00:00:00 2001 From: stempeck Date: Tue, 15 Sep 2026 22:29:42 -0400 Subject: [PATCH 1/4] Token economics for the factory: account for what each run costs its own context window and act on it. Adds a pre-act sub-agent dispatch gate over declared backend pools, efficiency actuators independent of window room, split SessionStart writers with per-session mail delivered-state and identity parity gates, generation telemetry with band and compare verbs, grader visibility of harness interventions, a watchdog latch and alarm terminus, dispatcher crons, mergepatrol merge authority, and formula, skill, doc, and test hardening.

It asks a +different question: not whether the next step will fit, but what that step has historically +**generated** — output tokens, exact thinking tokens, sub-agent tokens, and how often it re-read a +file it had already read. A step that fits its window with room to spare can still cost twice what +it needs to, and no occupancy reading can see that. Guarantee 7 is why a roomy window cannot switch +this arm off. + +It is a closed loop — **observe** what a run held and what it generated, **evaluate** a pure +arithmetic policy, **act** through a fixed vocabulary of mechanisms, **record** every firing as an +auditable intervention. This section is the contract for the third and fourth steps. +`af tokenomics --help` and `af tokenomics status` both point here. + +```bash +af tokenomics status # Policy table, resolved window, arithmetic inputs, why it is inert +af tokenomics status --json # The same, machine-readable (always exits 0 — branch on .state) +af tokenomics on # Never gated: oversight fails toward being on +af tokenomics off # Operator-only, from a host shell +af telemetry report --json # Per-step occupancy AND what each step generated +af telemetry band # Observed figures against learned medians, with the band stated +af turn interventions --since --agent # What the harness did to one agent this turn +af telemetry compare --formula --surface a|b --before --after # Did a change help? +``` + +### What the harness guarantees + +1. **No step is ever blocked; one launch may be, by one enumerated gate.** No mechanism refuses a + *step*, fails a hook, or holds a session, and every hook in the loop still exits 0 (ADR-007) — the + advisory mechanisms can only counsel, hand off at a boundary, or start the *next* session at a + reduced effort level. The single enumerated exception (ADR-007 amendment, 2026-08-31) is the + pre-act sub-agent-dispatch capacity gate: it may deny *a new sub-agent launch* — never a step, + never any other tool call — through the PreToolUse permission-decision channel, not a non-zero + exit. It refuses by arithmetic over an operator-declared backend pool — including a + child-footprint floor (`AF_BACKEND_CHILD_FLOOR_TOKENS`, default 50k) that guards the first child + near the ceiling and counsels `af handoff` when the launcher's own session alone leaves no room — + or, where the profile sets `AF_DISABLE_PARALLEL_SUBAGENTS`, by a hard semaphore of one that + refuses a second sub-agent while a sibling still runs. It fails open on any resolution error, and + is structurally inert where no capacity fact is declared (every cloud profile). +2. **No tokenomics mechanism interrupts work in flight.** When one of these mechanisms recycles a + session it does so only at a step or formula boundary, after the closing record is written and + before the next step opens, so there is no partial work to lose. This is a claim about *this* + loop and not about the whole harness: the context-exhaustion ladder does recycle mid-step — under + its own `context_exhaustion` trigger, which the two respawn-attribution classes below deliberately + exclude — and `af prime`'s economics block tells an agent to expect exactly that when a handoff + would not help. +3. **Every firing leaves a record, or the contract says it leaves none.** A mechanism that acted and + left nothing behind is indistinguishable from one that never ran; the table below names the record + for each mechanism, and says "none today" where there is none. +4. **No verdict is ever stored.** Records carry figures; every judgement — over-occupancy, + over-consumption, within-baselines — is recomputed at read time from those figures alone. A + figure cannot lie and a verdict computed under one version of the rules can. +5. **The umbrella is a conjunction and either half silences everything.** `af tokenomics off` (the + `.agentfactory/.tokenomics` toggle) and `tokenomics.enabled: "off"` in `startup.json` each veto + the whole surface, including a mechanism an operator switched on explicitly. Every toggle write is + appended to `.agentfactory/.tokenomics.log` as one `ts actor source state` line. +6. **Off is the default.** A factory that has never run `af tokenomics on` runs none of this, and its + per-verb cost is one gate-file read. +7. **Efficiency actuators read no window operand.** The predicate the efficiency arm consults takes + an aggregate of what a step has historically generated, whether that aggregate was found, and the + resolved policy — and nothing else. It is handed no context window, no live occupancy, no declared + pool, and it has no way to ask for one. That *absence* is the guarantee, not an omission from it: + a roomy profile cannot silence this arm, because the function never learns how much room there + is. Every mechanism the capacity arm owns goes quiet on a cloud profile by design; the efficiency + arm is the half that does not, and it stays that way only for as long as the operand list does. +8. **No efficiency intervention edits a formula.** The efficiency mechanisms counsel a session, + recycle it at a boundary and start the next one at a lower effort level — they change how a step + runs, never what the step *is*. Nothing under this umbrella writes a formula. The one loop that + does change a formula is the continuous-improvement loop under its own umbrella, where the edit is + made by the agent under the improvement hook's static instruction and closed by + `af improvement complete`, which validates it and mails the verdict. Where the two umbrellas meet, + tokenomics contributes exactly one sentence of preference to that instruction and no number — it + can ask the improvement loop to favour edits that remove re-reads, and it cannot make one. + +### The permitted actions + +The design names four advisory interventions — defer the step, serialize a fan-out, recycle the +session at a boundary, inject guidance — and they map onto three recorded actions. The ADR-007 +amendment (2026-08-31) then enumerated a fourth thing the harness may do: refuse a sub-agent launch. +The vocabulary of things it may *do* is therefore deliberately **closed at four**, because there are +exactly four things this harness can do — tell a session something, end its turn, change how hard it +thinks, or deny it a launch. A fifth `Action` constant, `observe`, records the opposite of an act. +The mapping is the contract: + +| Intervention (design language) | Recorded action | What actually happens | +|---|---|---| +| `defer` the step | `advise` | The agent is told, at prime, that the step's learned appetite does not fit the free window. It decides — nothing holds the step. | +| `serialize` a fan-out | `advise` | Either advisory text at prime, or one urgent self-addressed `TOKENOMICS_DISPATCH` bead relaying a refusal the `af dispatch-admit` gate has already recorded, counselling that sub-agents go out one at a time. The observer that delivers the bead computes nothing: it restates the gate's recorded figures. | +| `guidance`, injected | `advise` | Advisory text rendered into the prime output and recorded as a firing. | +| `recycle` at a boundary | `handoff` | The session is replaced at a step or formula boundary, carrying a resume brief in the checkpoint. | +| *(not among the design's four)* | `reduce_effort` | The D16 arm: the relaunched session inherits a declared, lower effort level. | +| *(ADR-007 amendment; not among the design's four)* | `refuse` | The pre-act sub-agent-dispatch capacity gate (`af dispatch-admit`) denies a `Task` launch that would oversubscribe the backend's declared pool, through the PreToolUse permission-decision channel. The refused agent is shown the arithmetic and counselled to launch one at a time; the refusal is recorded regardless of the telemetry toggle, carrying `pool_tokens` and `summed_occupancy_tokens`. | +| *(not an intervention at all)* | `observe` | An armed site reached its decision point and changed nothing, and says so rather than leaving silence. Two write it: the pre-act gate when it fails open because the arithmetic could not be assembled — carrying no operands, because the missing operands *are* the fact — and the efficiency boundary when a relaunch history warranted was refused by the per-instance relaunch bound. `af tokenomics status` tallies these separately and never as firings, and attributes them to no objective: a gate that could not judge must not be counted as one that did. | + +The fourth `Action` constant, `refuse`, exists because the ADR-007 amendment (2026-08-31) widened what +the harness may do by exactly one enumerated act — denying a sub-agent launch — not because prose +needed reconciling. It is the one and only widening of what the harness may *do*. `observe` is a fifth +constant and not a fifth act: it is the record for having declined to act, which is why introducing it +did not require an amendment and why an actual new act still would. + +### Per-mechanism contract + +Each mechanism is named here by its code constant (`internal/tokenomics/policy.go`), which is the +same string `startup.json`, `af tokenomics status` and the intervention records use. + +Three of the six fire at more than one site, and the sites do different things. Where that is so the +row names each of them, because an operator grepping intervention records will find each. + +Naming a second site is never a second verdict. Where a mechanism gates something, exactly one site +computes the verdict and the others either counsel from a different question or relay what that site +recorded. For `dispatch` this is the whole of issue #673 item 1: the pre-act gate computes, the prime +advisory asks a different question (does this *step* fit its own window), and the `Task`/`Agent` +observer relays. Two computers would mean two answers, and the divergence would be invisible because +neither logs the other's operands. + +The `Objective(s)` column names which arm of the accounting each mechanism answers to, spelled as the +`objective` field on its intervention records. A row naming both fires for two independent reasons and +one arm going quiet does not silence the other. + +| Mechanism | Trigger | Guarantee | Permitted action | Audit record | Objective(s) | +|---|---|---|---|---|---| +| `budget` | The admission predicate, at `af prime` (open time) and `af done` (close time): the step's learned appetite projected against the free window exceeds the admission margin | Never refuses the step; recycles only at a boundary, and only when a fresh window would actually fit | Advise at prime; hand off at a step or formula boundary | Two record classes — `mechanism=budget` with `action=advise` at prime (`prime_economics.go`), and with `action=handoff` at the boundary (`done.go`) | `capacity` | +| `thrift` | Two independent triggers at prime. The capacity trigger keys on the session's **current occupancy alone** being at or above the admission ceiling — no learned history is required, which is the point: it is the one capacity trigger that still applies in a factory that has learned nothing. The efficiency trigger keys on the step's learned median `repeat_reads` crossing the policy's threshold — once the efficiency arm is on and the step has a trusted aggregate with generation figures in it, which are the predicate's preconditions for answering anything — and it reads no occupancy, no window and no pool at all | Text only — it changes nothing about the run. The efficiency counsel is gated on the efficiency plan alone and not additionally on the thrift switch, so an operator who turned capacity-thrift off still gets the re-read counsel: the two answer different questions and neither switch speaks for the other | Advise: prefer targeted reads, do not re-read what is already in context | One `intervention` record per firing, `mechanism=thrift`, `action=advise` (`prime_advisory.go`) — both firings carry the same mechanism, so the `objective` field is the only thing that tells them apart. The efficiency counsel is deduped once per step under the composite `thrift\|efficiency` key rather than under the bare mechanism, because one spelling would let the capacity thrift suppress it | `capacity`, `efficiency` | +| `dispatch` | Three sites, one verdict. At prime, when the step fits the free window but only just (learned appetite ≤ free < 2 × appetite) — that is step-appetite counsel, a different question from pool capacity, and it is why a third `mechanism=dispatch` emitter does not make a third decider. At every `Task`/`Agent` completion, through the `af subagent-observe` PostToolUse hook, when the gate has left a recorded refusal newer than the 15-minute fan-out latch window — the observer relays that recorded decision and computes no capacity verdict of its own. And pre-act, through the `af dispatch-admit` PreToolUse `Task\|Agent` gate — the one site that computes the capacity verdict — when a launch would oversubscribe the backend's declared shared pool, leave less than the child-footprint floor (`AF_BACKEND_CHILD_FLOOR_TOKENS`, default 50k) free, or — where `AF_DISABLE_PARALLEL_SUBAGENTS` is set — attempt a second concurrent sub-agent | The two advisory sites never block and always exit 0; the observer is latched, so one fan-out produces one counsel. `TOKENOMICS_DISPATCH` beads FOLLOW recorded refusals rather than anticipate them: the pre-act deny reason absorbed the pre-warning duty, so the bead is an after-the-fact restatement of a decision already made, not a prediction of one. The prime advisory reads the step's marginal appetite (its learned growth), so it is the design's soft, residual first rung; the PostToolUse observer and the pre-act gate — both appetite-free — are the deterministic serialization carriers. The pre-act gate is the ADR-007-amendment exception — it may deny the launch, and only that, by arithmetic over a declared pool (or by the sequential semaphore), failing open and staying silent otherwise (cloud-inert by construction). The sequential cap holds its slot for the child's whole lifetime: SubagentStop proposes; release follows verified sidechain quiet, never the stop signal alone | Advise: launch sub-agents one at a time and wait for each to return (prime renders this as text; the observer delivers it as a bead restating the figures the gate recorded). Pre-act: `refuse` the launch and tell the agent the arithmetic — counselling `af handoff` on a launcher-caused floor breach, otherwise to launch one at a time; a sequential-cap refusal names `AF_DISABLE_PARALLEL_SUBAGENTS` and says one sub-agent is already running | `mechanism=dispatch` with `action=advise` from `prime_advisory.go` or `subagent_observer.go`; and, on a refusal, `action=refuse` carrying `pool_tokens` (and `summed_occupancy_tokens` on a headroom or child-floor refusal; nil on the sequential-cap refusal, which is a semaphore, not token arithmetic) from `dispatch_admit.go` (recorded regardless of the telemetry toggle). The same refusal also leaves a `.runtime/dispatch_admit_last_refusal.json` breadcrumb, which is what the observer relays — it is a courier, not a second record. And where the gate fires open because the arithmetic could not be assembled, `action=observe` carrying no operands at all — the missing operands *are* the fact, and what the record is worth is the evidence that the gate ran | `capacity` | +| `interview` | Three sites. A boundary handoff, where the resume brief is composed for the replacement session — unconditional, and the only one of the three that is not policy-gated. At prime, when the interview arm is on and this session has been primed before, or the brief on disk was written for the step being started — the reduction withholds output the session already has (a slimmed identity block, a slimmed successor brief) and consults no efficiency plan, so turning the efficiency arm off does not silence it. And at a boundary relaunch the efficiency plan asked for a clean start on, where no coincident level change outranks the naming | The brief is written to the checkpoint before the pane is replaced. The prime reduction is recorded once per session and not once per invocation, so a session primed many times reads as one firing | Compose the resume brief; withhold output the session already holds; start the next session clean at a boundary | Three record classes, all `objective=efficiency` — `action=advise` at prime, latched once per session (`prime.go`); `action=handoff` at a clean-start boundary (`done.go`); and `action=observe` where the relaunch bound refused the recycle that boundary warranted, so a refusal is on the record as a non-event rather than as silence. The resume brief itself still writes nothing: it is not policy-gated and its evidence is the checkpoint | `efficiency` | +| `effort` | Three sites, two objectives. The actuator itself runs at the three launch legs (`af up`, `af sling`, and the respawn leg), where the efficiency predicate reads what the step has historically **generated** and chooses the level the next session will run at — the arm's primary trigger, and one that consults no window. Where that predicate declines, a capacity last resort may still select the policy's level for a step no session on the profile can hold. And at a boundary relaunch, where a level change is warranted — which outranks a coincident clean start in the naming, being the more specific fact and the only one of the two with a level to record | Nothing is re-levelled in flight: the level applies to the *next* session only, and the running one is never touched. The chosen level is clamped never to exceed what the profile itself declared, so where a profile declares a rankable level the arm can only ever ask for less; where it declares none, or declares `auto`, there is no ceiling to stay under and the plan stands | Choose the relaunched session's effort level; advise matching depth to headroom | Four record classes across three files, and exactly one of them reads its objective back rather than stamping it — so one prime can leave a `reduce_effort` stamped `efficiency` beside an `advise` stamped `capacity`, and a reader who folded the second into the efficiency arm would be counting a step nothing on the profile can hold as evidence that reducing generation pays. `done.go` writes two — `action=handoff` carrying `effort_level` at a boundary relaunch, and `action=observe` where the relaunch bound refused one — and stamps both `efficiency` outright. `prime_economics.go` writes the third, `action=advise` — the line printed at prime when the step failed admission, would not fit a fresh session either, **and** a level was already chosen for it, all three, and with the arm still on at the read site so that a session treated before the switch was thrown is not told it was treated — and stamps it `capacity` outright, because the sentence it prints is about a step no session can hold. `prime.go` writes the fourth, `action=reduce_effort` carrying `effort_level`, at prime, where the treatment was actually applied rather than at the boundary that scheduled it — a session that applied a level and recorded nothing would leave half the arm's firings out of the data the arm is judged on — and it is the one read off the launch breadcrumb, so it says `capacity` when the capacity last resort chose the level and `efficiency` when the predicate did | `efficiency`, `capacity` | +| `escalate` | Policy-routed escalation (K14) — deferred, and the one mechanism that defaults **off** even under an enabled umbrella | Cannot fire in this release | *(none)* | **none today** — nothing writes `mechanism=escalate`, so `af telemetry band` honestly reports zero escalated steps rather than implying it measured and found none | *(none)* | + +`effort` left the advisory registry, and the pairing that once made it and `dispatch` mutually +exclusive at prime went with it: the level it applies is chosen from the step's generation history at +the launch leg, not from what is left of the window, so it is no longer a window-pressure mechanism to +be exclusive *with*. The one thing it still says at prime is the capacity last resort's line, printed +by the economics block rather than by the registry — and that line reports a decision already taken at +launch rather than counselling one. `thrift`'s capacity arm can still accompany `dispatch`: "you are nearly full" and +"this step is large" are two different facts and a session can be in both — and the efficiency thrift +can accompany either, because it is again asking a third question. `budget` has a template in the +advisory registry and is +deliberately excluded from the prime counsel set, because its own economics block renders the same +arithmetic at the same moment and firing both would say one thing twice. + +### How improvement is proven + +A change to this surface is claimed to have worked only when `af telemetry compare` says so. Every +other reading of the record log — `af telemetry report`, `af telemetry band`, `af tokenomics status` — +is a diagnostic, and none of them is the bar. + +The bar is **`median(after) < min(before)`**, strictly, over two arms of 5 runs each. Not mean against mean, +which one long run dominates, and not median against median, which passes on a coin flip: requiring +the after arm's median to fall below the *cheapest* before run is what makes it hard to clear by luck. +Under a pure-noise null it takes the three cheapest of the ten runs all landing in the after arm — +**21 of 252 splits**, about 8.3 % — and the verb prints those odds beside the verdict whenever the arms +hold counted runs, rather than leaving a reader to look them up; on empty arms it says instead that +there is no false-pass rate to state. A short arm is not a `fail`: nothing was disproved, so nothing +may be claimed. + +The metric is Σ over closed steps of output tokens plus sub-agent tokens, and nothing else is ever +added to it. Thinking volume travels beside the verdict as a diagnostic and is deliberately not summed +in, because a pass metric that included it would measure how hard the model thought rather than what +it produced. + +The verdict is one of `pass`, `fail` or `void`, and a failed precondition **voids rather than fails**: +`fail` is a claim about the intervention, `void` is a claim about the comparison, and a comparison +whose arms were not held fixed says nothing in either direction. Each void names the checks that +caused it, from a closed vocabulary — `distinct_runs`, `arm_size`, `formula_matches`, +`run_completion`, `steps_closed_constant`, `measured_steps_cover_closed`, `af_commit_constant`, +`model_constant`, `host_version_constant`, `checkout_commit_constant`, `input_digest_constant`, +`input_digest_verified`, `base_commit_matches_checkout`, `formula_digest_constant`, +`tokenomics_state_per_arm`, `nesting_comparable` — because a "void" with no named check is exactly the +unfalsifiable refusal the verdict exists to replace. + +Two surfaces can be measured and `--surface` says which: + +- **Surface B** holds the formula fixed and moves the posture. One formula digest spans all ten runs; + the before arm runs `af tokenomics off`, the after arm `af tokenomics on`. +- **Surface A** holds the posture fixed and moves the formula. The arms run two *different* formula + digests, with tokenomics on and `af improvement off` throughout — the arm measures the edit, not a + live loop, because a digest that moved mid-arm would leave nothing fixed to compare. + +The `--input-digest` attestation is part of this procedure and nothing else: the **operator** runs +it **by hand**, **during these measured-verification runs** — at sling time (step 3) recording the +canonical `sha256` of the frozen inputs on each run, and at compare time (step 7) re-checking it with +`--verify-input-digest` — **so that** both arms are proven to have run on byte-identical inputs and +`compare` voids any run whose inputs drifted rather than reporting a difference the drift could explain. + +The procedure, in the order an operator runs it: + +1. Build once, so both arms record the same `af_commit`, and `af telemetry on` for both. Pin + `tokenomics.learned_min_runs` in `startup.json` to at most the arm size of five and record the + value: the shipped default is 2, but a factory that had raised it would run its whole after arm + dark. +2. Pick a **closed** issue and freeze the input. Commit the problem summary into the pinned SHA so the + formula takes its coordinator-input path and never fetches live, and attest the issue body and its + comments with a canonical `sha256` — field order and comment order pinned, so two honest + attestations of an unchanged issue cannot differ. +3. Freeze the remote. Clone a bare mirror outside every worktree, point its `main` at the pinned SHA, + and set each run's `origin` to that mirror, so the formula's own fetch and rebase land on the pin. + Each run gets a fresh worktree from the pin in its own agent directory, and is slung with + `af sling --formula --input-digest `. +4. **Surface B**: five runs with `af tokenomics off`, then five with `af tokenomics on`, + `af improvement off` throughout. The before arm is what seeds the digest, which is why step 1 caps + the trust floor at the arm size — with it, every key is trusted from after-run 1. `compare` prints + `trusted_keys` per run, so a dark arm cannot pass unnoticed. +5. **Surface A**: one intersection run with both loops on produces the edit; the operator reads the + outcome mail and promotes it or keeps the store edit. Then five **counted** runs on each digest, + improvement off and tokenomics on in both. Budget `learned_min_runs` further runs at the head of + the after arm: they seed the new digest partition, they are recorded and excluded, and they are + *additional to* the five — the `arm_size` check voids any arm that does not hold exactly five + counted runs, so warm-ups taken out of the five produce a `void` rather than a result. The after + arm's keys are therefore only just trusted where the before arm's are long trusted, an asymmetry + that favours the *before* arm and must not be read as a marginal after-arm effect. +6. Before committing to an arm, three pilot runs on the pinned fixture establish the same-issue spread + and test a stated prediction. `compare` prints that spread as `before_spread_pct` and the reduction + the bar actually demands as `required_reduction_pct`, because a 1.6× within-arm spread and a 2.5× + cross-issue spread ask very different things of the same intervention. +7. `af telemetry compare … --verify-input-digest ` after the last run. What that + flag re-checks is the attestation `af sling --input-digest` recorded on the run as `sling_digest`, + surfaced by `compare` as `input_digest`; a `void` names what to re-run. + +Reading a `fail` is part of the protocol rather than an exception to it. If the actuators fired and +the targeted steps show `outside_baselines` with `direction: below` under `af telemetry band` while the total still misses, the +bar was missed — an accepted residual, and the intervention worked as far as it reaches. If the +actuators were dark, or the targeted steps did not move at all, it is a design defect and the arm +sizes have nothing to do with it. The two readings call for entirely different work, which is why the +per-step direction is printed beside the total instead of folded into it. + +### Residual ceilings and disclosures + +These are the limits of what the surface can tell you. They are written here rather than left to be +discovered, because each one has a failure mode where a reader would otherwise draw a stronger +conclusion than the data supports. + +- **The learning plane is local, and permanently so.** Every figure the policy reasons about comes + from `.agentfactory/telemetry/` and from Claude Code session transcripts on the same host. The + telemetry *backend* cannot supply them: `af telemetry usage` returns `query_failed` for the + per-step token columns because the backend's logs stream does not carry them. That is a known gap + in the backend, not a fault in the factory or the console — and it means a factory whose telemetry + export is healthy still learns nothing from the backend. +- **Fail-open means ADMIT.** When there is no occupancy reading, no resolved window, or no learned + data for a step, the admission predicate answers `observe` rather than `no-fit`, and the step + proceeds. "We have no basis to judge" and "we judged, and it fits" are kept as different answers + in the record, but they have the same effect on the run: nothing is held. An operator who expects + a step to be blocked when the harness is blind will be surprised in the safe direction. +- **The fidelity grader also fails open, and does so more often on offline profiles.** + `hooks/fidelity-gate.sh` invokes the grader through an `env -i` allowlist that deliberately strips + cloud credentials; when the grader returns an empty verdict the gate notifies once and never + blocks. On a profile with no reachable grader, turns pass ungraded rather than failing. +- **Respawn attribution has two named funnel classes and they are not interchangeable.** A session + replaced out of a channel that had already gone quiet records `backend_stall_respawn`; one replaced + out of a healthy channel records `unattributed_respawn`. A count that merges them cannot tell a + backend dropping sessions from something else entirely, and the two call for different + investigations. +- **`bound_tokens` is a telemetry annotation, not the denominator.** The `step_context.bound_tokens` + value in `startup.json` is recorded on each step as `ctx_bound_tokens` so a reader knows what the + step was judged against, but the window every occupancy fraction is divided by resolves **per + agent** — declaration, then the host's report, then the fallback — and travels with a source field + saying which of the three it was. On a mixed-profile factory a single `bound_tokens` is not the + window for every agent, and a report that treated it as one would be comparing agents against a + number none of them ran under. +- **Escalated-step counts read zero on every honest factory today.** There is no escalation marker in + the record schema; the only derivation is counting intervention records whose mechanism is + `escalate`, and nothing writes one. `af telemetry band` states that reason beside the zero. +- **Statusline profile resolution is config-only.** It passes no CLI model and does not read + `.runtime/model_override`, while the prime/done path is marker-aware. On a session whose model was + overridden at launch, the statusline's window and the record's window can name different profiles. +- **The pass metric cannot see input-side savings.** It is Σ of output and sub-agent tokens, so an + intervention that removes *input* — the re-prime slimming that withholds output a session already + holds, or counsel that stops a file being read twice — scores exactly zero on the bar unless it also + shortens what the model then generates. That is the intended shape of the metric and not an + oversight: input savings are cheap to fake by truncating context, and a bar that rewarded them would + reward the truncation. It does mean a `fail` is not evidence that a slimming change did nothing, + only that it did nothing the bar measures. Where that question is actually answered is + `af telemetry compare --json`, which carries `in_tokens` and `cache_read_tokens` beside the verdict + — per **run**, not per step, so the answer is coarser than the verdict it qualifies. + `af telemetry report --json` carries neither of those two columns. The nearest it does carry per + step is `cum_tokens_delta`, which *is* a spend figure — the difference across the step, and the + direct answer to what the step cost — but a total one, so it cannot separate input from output and + cannot tell a slimming change from a shorter answer; and `ctx_tokens_start`, which is occupancy, + what the window held rather than what was paid to fill it. +- **Effort is session-granular, and the metric is per run.** A chosen level applies to the *next* + session, so a step that runs start to finish inside one session never sees the level move, and a + session that spans several steps applies one level to all of them. The arm therefore cannot be + credited or blamed per step: `af telemetry band` will show `direction` per step, but the attribution + from a level change to any one of those steps is an inference the records do not carry. + +### Where the numbers come from + +`af telemetry report --json` carries, per step, four different things and it is worth keeping them +apart: what the window *held* (`ctx_tokens_start`, `ctx_tokens_end`, `ctx_tokens_total`, +`ctx_used_pct`), what the step *generated* (`out_tokens`, `think_tokens_est`, `thinking_share`, +`peak_ctx_tokens`, `subagent_tokens`), what the step *cost* (`cum_tokens_delta`, a total spend +figure), and what it was *judged against* (`ctx_bound_tokens`). The last two are why the row carries +two verdicts rather than one: `over_occupancy` compares what was held to the bound, +`over_consumption` compares what was spent to it. Every one +is an explicit `null` when it was not measured, never a `0` — "nobody measured this" and "this was +zero" are different facts and the schema keeps them apart. + +Token counts are derived under one counting rule, and it is not obvious: Claude Code writes **one +record per content block** and stamps the whole message's usage on every one, so records are reduced +per `message.id` with **MAX per field** — not summed, which over-counts by roughly 2.2×, and not +first-wins, which keeps an in-flight partial and drops the completed count. Any figure quoted about +this factory that was produced by summing transcript lines is wrong by about that factor. + +The figures a measured verification run is graded against are registered in +`internal/telemetry/verification_baselines.go` — each with its unit, whether it is a wall cost or a +share, and the exact file and line it was derived at — together with that counting rule and the +sha256 procedure for proving a run's artifacts are the ones it reports. They live in ordinary source +rather than in a test so they can be read and cited without running anything, and they are pinned +before a run rather than chosen after one. + +`af telemetry rebuild` folds closed step records into a learned digest — per (formula, step, model) +medians, maxima and thinking share — which is what the admission predicate's "learned appetite" reads +and what `af telemetry band` judges a run against. `af tokenomics status` reports how many aggregates +that digest holds, and says so explicitly when it holds none rather than printing a bare zero. + +## The efficiency knobs in `startup.json` + +Efficiency is the eighth tokenomics switch and deliberately **not** a seventh mechanism +(`internal/config/startup.go`): the six mechanisms are capacity behaviours keyed on window pressure, +while efficiency is keyed on a step's learned generation history and fires at any pressure at all. +Five keys under the `tokenomics` block in `startup.json` configure it — set them with +`af config startup set`.

A written `0` reads as this block's "unset" spelling and fills to the default — it is **not** a "disable relaunches" value. To stop efficiency relaunches entirely, set `tokenomics.efficiency off`. | diff --git a/docs/architecture/adrs/ADR-007-hooks-never-block.md b/docs/architecture/adrs/ADR-007-hooks-never-block.md index 41bbfb0..85cc3c5 100644 --- a/docs/architecture/adrs/ADR-007-hooks-never-block.md +++ b/docs/architecture/adrs/ADR-007-hooks-never-block.md @@ -1,8 +1,12 @@ # ADR-007: Hooks never block; enforcement is via mail to agent inbox; no escalation into a void -**Status:** Accepted (extended 2026-06-15 — "no escalation into a void"; see *Amendment* below) +**Status:** Accepted (extended 2026-06-15 — "no escalation into a void"; amended +2026-08-31 — one enumerated exception: the dispatch capacity-admission gate, +#672; see *Amendments* below) **Date:** 2026-03-23 (quality-gate `dac416a`); 2026-04-10 -(fidelity-gate `871e9f9`); extended 2026-06-15 (no-escalation-into-a-void) +(fidelity-gate `871e9f9`); extended 2026-06-15 (no-escalation-into-a-void); +amended 2026-08-31 (enumerated exception — dispatch capacity-admission gate, +operator decision — #668/#672) ## Context @@ -110,6 +114,62 @@ mechanism. condition it reports. - "Hooks never block" and gate→own-inbox routing are unchanged. +## Amendment (2026-08-31): One enumerated exception — the sub-agent dispatch capacity-admission gate (#672) + +**Status:** Accepted (operator decision, 2026-08-31).

Before #675, one hook entry carried all of it: a single +`&&`-chained command that ran `af prime --hook`, which rendered the role template (identity), then +shelled out to `af mail check --inject`, with memory appended after. One command, one output string, +one budget, four writers competing inside it. + +Three facts made that topology fail, and it failed silently. + +**The harness truncates a hook's output string.** Measured across the full transcript population +(8,949 hook-output rows, recipe `.analysis/675/scratch-15/hooksweep.jq`), the boundary between +"delivered whole" and "spilled to a file and replaced by a preview" falls between the largest +observed inline value and the smallest observed spilled one: **(9,949, 10,128] Unicode code points**, +or **(9,992, 10,259] bytes** for the same rows. Both brackets are gap-free and both straddle 10,000, +so both are consistent with a ~10,000 cap. + +**The corpus does not determine which unit the cap counts**, and it cannot: UTF-8 byte length is +always ≥ code-point length, so no observation separates the two hypotheses. Treat the unit as +unknown. What follows from that is a choice, not a measurement — **af's budgets are stated and +enforced in bytes** (`len(Emit(n))` against `TotalBytes`, `internal/memory/slice.go:178-186`; +`len(renderMailEntry(…))` against `mailInjectTotalBytes`, `internal/cmd/mail.go:611-615`) because +bytes are the conservative unit under either hypothesis: a block that fits a byte budget fits the +same number of code points, but not the reverse. Where this ADR states a size in code points — the +K12 figures below — it does so because that is the *smaller* of the two numbers and therefore the one +that could still be under a cap the byte count exceeds; each is given with its byte count beside it. + +**One of the writers cannot be bounded.** A formula step's `description` is the formula author's +contract and af reproduces it verbatim (C-2). It is not af's text to trim. With everything in one +string, a large step description did not degrade gracefully — it evicted the *other* writers. + +**Nothing noticed.** There was no per-writer budget to exceed, no assertion over the composed +output, and `af telemetry` records no SessionStart context fields at all. An agent that opened a +session with its mail silently dropped looked exactly like an agent with no mail. + +The compounding problem: identity was the largest and least necessary occupant of that string. The +harness already loads the agent's own `CLAUDE.md` at session start. Prime was re-sending, into a +capped channel, text the model was about to receive anyway — and crowding out mail and memory, +which have no second carrier, to do it. + +## Decision + +**(a) SessionStart context is three independent writers, one hook entry each.** *(design decision +D-1 — what SessionStart context is.)* `af prime --hook`, +`af mail check --inject`, and `af memory check --inject` are registered as three separate entries on +the same `SessionStart` matcher, for **both** role types, emitting through the structured +`hookSpecificOutput.additionalContext` channel +(`internal/claude/config/settings-autonomous.json:49-67` and the interactive twin; the two are held +command-for-command equal on this block by `internal/cmd/using_hook_table_test.go`, which compares +the commands after stripping each entry's `export PATH=… && ` preamble — not the raw bytes). There +is **no shared budget**: +the harness's unit of truncation is the output string, so one entry per writer makes each writer's +ceiling its own. Mail's block is capped at **4,608 B** (`mailInjectTotalBytes = 4096` + +`mailInjectFrameBytes = 512`, `internal/cmd/mail.go:522,530`); memory's at **4,736 B** +(`memory.DefaultTotalBytes = 4096`, `internal/memory/slice.go:24`, + `memoryInjectFrameBytes = 640`, +`internal/cmd/memory.go:54`). Neither can now be evicted by the other or by the step body. + +**(b) Identity delivery is deliberately multi-carrier, and the SessionStart hook is not one of the +carriers.** *(design decision D-2 — who owns identity delivery.)* Identity reaches the agent by three paths. Two are unconditional: the harness's own load of the +agent's `CLAUDE.md`, and af's re-render of that file at every provisioning site, including recycles +(`internal/cmd/install.go:607,1118`, `internal/worktree/worktree.go:574`, +`internal/cmd/recovery.go:1110`). The third — a **plain** `af prime`, the tool-result kind an agent +runs itself, which renders the role template whole — is *conditional*, and the condition is the +whole of the gate at `internal/cmd/prime.go:287`, `!primeHookMode && !slimIdentity`. `slimIdentity` +is #678's re-prime reduction: when the tokenomics interview mechanism is on it slims every prime +past the session's first (`prime.go:269-271`). That mechanism is umbrella-gated and comes on *by +default* once the umbrella is on (`internal/tokenomics/policy.go:157,175-177`), and the SessionStart hook +prime is itself counted, so with the umbrella on the first plain prime an agent runs is already +prime #2 and is slimmed. OD-1's "identity in every tool-result prime" therefore holds exactly in the +shipped default — umbrella off — and not under a configuration an operator is expected to choose. +The hook path carries none of it in any configuration, because a channel that truncates is a +fragment channel, and a fragment of an identity is worse than none. **No on-demand identity flag +exists** and none was added: the recovery path is the two unconditional carriers, which is why it +matters that they are the unconditional ones. The deployed corpus is +held byte-equal to the embedded templates by +`TestDeployedAgentIdentityMatchesEmbeddedTemplate` (`internal/cmd/identity_parity_test.go:49`) — the +gate that makes "the harness loads `CLAUDE.md`" a guarantee rather than a hope. + +**(c) Mail delivered-state is session-scoped and never enters the store.** *(design decision D-4 — +delivered-state location and key. Rejected: a label or `Read` flag on the message, which makes +delivery a durable mutation; and a creation-time watermark via `CreatedAfter`, dominated by the +inclusive bound and by status transitions.)* What a session has +already been shown is recorded in `.runtime/mail_delivered`, keyed on the session id the hook itself +supplies. Mail is not mutated, so nothing about a message's durable state depends on a hook having +run. Deleting the file re-delivers everything once — fail-open, because the failure mode of +over-delivery is noise and the failure mode of under-delivery is an agent that never learns it has +work. + +**(d) The formula step body is the one unbounded writer, and the tool-result `af prime` is its +guaranteed channel.** af does not trim a step description. `af prime --hook`'s entry may therefore +be truncated for a large step — and after (a), that costs nothing from mail or memory.

If the bracket moves, the budgets in (a) move +with it. E1 and E2 are the two this design would actually change shape for; E4 turning false would +cost identity after compaction and is the one to watch. + +**(f) `9278bfd` is superseded for hook-mode identity only.** That commit +(`docs/architecture/subsystems/cmd.md:68`) made prime's context injection unconditional because +"agents lost formula context on every compaction". Its **formula-context** rationale stands +unchanged and is why (d) keeps the step body in the hook entry. Its **identity** half is superseded: +identity no longer rides the hook, because E4 plus (b)'s re-render make it unnecessary there. + +**(g) Sub-agent and grader sessions fire the chain too** — measured, not assumed. They are excluded +from delivered-state by construction: (c) keys on the session id the hook supplies, and delivery is +additionally refused when the payload's transcript path contains `/subagents/`. Whether a sub-agent's +id is ever the parent's is UNPROVEN — the K11 payload-capture check that would settle it was not run — +so the `/subagents/` refuse guards the residual case (a sub-agent SessionStart carrying the parent's +session_id) rather than relying on the ids differing. A session with no id claim emits without recording. + +**(h) The telemetry blind spot is accepted and named.** Half the instrumentation exists and is worth +knowing about: `recordPrimeCost` (`internal/cmd/prime_economics.go:75-104`) persists prime's own +block size and token estimate per session. But it covers **prime only** — mail and memory record +nothing — and it is **write-only**: no read surface selects those fields, so no report, threshold or +alert consumes them. The practical consequence stands: **no runtime signal exists** for a +SessionStart-size regression, and the K9 CI test is the only catch. Anyone widening a SessionStart +writer without extending that test is working without instrumentation. Closing this properly means +giving mail and memory the same recording and then building a reader — the second half being the part +that has never existed. + +### The K12 step-size rule + +**A formula step description longer than the per-string cap is delivered whole only by the +tool-result `af prime`** — the one an agent runs itself. `af prime --hook`'s entry may be truncated +for such a step; because of (a), mail and memory are unaffected. Treat a step description that +approaches the cap as a formula-authoring smell, not a delivery guarantee. This rule is documentation +only: the authoring-time warning, the truncation detector and the largest-step calibration report +were all considered and cut (OD-4), so nothing enforces it mechanically. + +Sizes are `len(description)` in **Unicode code points**: the smaller of the two counts and so the +more forgiving reading of E1's undetermined unit, since a step that is over the cap in code points is +over it either way. When this ADR was written, several step-bearing formulas in +`internal/cmd/install_formulas/` had a first step over 4,000 code points and the largest single step +was over twice the cap. The figures themselves are deliberately not recorded: they drifted materially +between the design and this ADR, inside a single issue's lifetime, and that drift is the argument for +the rule. Recompute them over the live corpus (parse every `*.formula.toml`, measure each `[[steps]]` +description) rather than transcribing any stated number. + +## Consequences + +**What this buys.** Mail and memory now have ceilings that hold regardless of what any other writer +does — the property the single-chain design could not offer at any budget. An empty vault or an empty +mailbox costs nothing. Identity survives compaction through E4 and the re-rendered `CLAUDE.md` +without spending a byte of the capped channel, and the file it survives through is now gated +(`identity_parity_test.go:49`) rather than assumed. + +**What it costs.** + +- **Three entries to keep in step, not one.** Settings templates, both role types, and the operator + manual's hook table must agree. `internal/cmd/using_hook_table_test.go` holds the doc against the + JSON; nothing holds the JSON against a future fourth writer. +- **A wider derivation surface.** The Memory Protocol text agents read is a Go const + (`internal/templates/memory_protocol.go`) baked into 41 generated templates, hand-mirrored into 2 + built-ins, and rendered into 43 deployed `CLAUDE.md` files — 86 derived artifacts from one const, + three byte-equality gates, two packages. #515 shipped exactly this edit to 40 of 42 deployed files and left the + built-ins stale for a month. The third gate exists because of that incident. +- **No ordering guarantee** (E6). Any future writer that needs to read another's output is + incompatible with this topology. +- **A documentation-only rule** (K12) with no enforcement, by decision. +- **The blind spot in (h)**, carried deliberately. + +**Rejected alternatives** *(design decisions D-1 and D-3 — topology and output channel).* *One owned +verb with one budget* reverses `.designs/515:151,159` and +cannot fit a step body beside mail and memory at any split. *One `&&` chain with three writers and a +shared sum* leaves memory's survival dependent on prime's size, which C-2 forbids bounding — it is +the design that failed. *Plain stdout per entry* is the recorded fallback if E2 ever proves false; +it is not the default because E3 leaves per-command separation of plain stdout undocumented, while +the `additionalContext` field shape is documented and has three encoder precedents in the tree. + +## Flip condition + +If E1's bracket moves far enough that the cap stops binding — a harness that delivers 100 KB hook +strings whole — the *reason* for one-entry-per-writer weakens, and folding the entries back together +becomes arguable on simplicity grounds.

DELETE the old derived file FIRST via `git rm `, so neither the working tree nor + git's staging area carries the old content (history keeps it recoverable) and no old + misinformation or bias can enter the regeneration; forbid the regenerator from reading + prior derived artifacts as sources. +2. Spawn a sub-agent with the Agent tool whose prompt IS the operator's dictated sentence + VERBATIM — "Use the skill tool to load and run /design-plan-impl on /design-doc.md" + (substituting the project's planning skill) — with NOTHING prepended and NOTHING + appended. No source-of-truth glosses, no constraint lists, no return-format demands: + if the run needs accompanying commentary to come out right, the documents are not + self-sufficient, and THAT is the defect to fix. Anything beyond the sentence requires + the operator's own dictation. +3. If the operator's governed pipeline runs elsewhere (e.g. a dispatched factory agent), + hand the operator the exact dispatch command instead — never substitute a different + runner without asking. + +**(b) Full rewrite in place.** If regeneration is unavailable in this environment, rewrite +every affected phase/section so each is self-contained and consistent with the source — an +extractor reading ONLY that section must build the current design, not the superseded one. +Re-verify every file:line citation your edits touch against the live tree; explicitly mark +anything you did not re-verify as `[not re-verified]`. + +**GATE:** run the same contradiction sweep on the plan, PLUS the extraction test: read each +phase section in isolation and record a per-section verdict row in the ledger file — +section name → one superseded term searched → ABSENT/FOUND. A section without a row was +not tested; a FOUND row loops back to the rewrite before this gate can pass. + +### Phase 5 — Independent Peer Review (MANDATORY) + +Spawn a sub-agent with the Agent tool (general-purpose). Its prompt IS this sentence +VERBATIM, with nothing prepended and nothing appended: +"Use the skill tool to load and run /rootcause-review on /implementation-plan/implementation_plan_outline.md" + +It must NOT receive this conversation's rationale, the ledger, or any summary of the +decisions — the entire value of this step is uncontaminated eyes reading what is actually +on the page, the way the next agent consumer will. Wait for its completion. + +### Phase 6 — Feedback Loop + +Read the review's appended findings. For each finding, exactly one of: +- **FIX** — re-enter the Phase 3/4 rules for the edit (impact-map the fix, sweep after), or +- **ESCALATE** — a finding that contests an operator decision goes back to the operator as + a plain-language AskUserQuestion. Never silently reverse an operator decision because a + reviewer disliked it; never silently dismiss the reviewer either. + +Record a disposition table in the ledger file — one row per finding: finding → FIX (with +the exact edit anchor: file plus the old→new fragment) or ESCALATE (with the question +asked and the answer given). A finding without a row is ignored, and ignoring is banned. + +Maximum TWO review cycles (re-spawn Phase 5 after a FIX round). Findings still open after +cycle two go to the operator in the final report, stated plainly — and any fixes applied +AFTER the final review round are named there as reviewer-prescribed but unverified. + +### Phase 7 — Handoff + +Stage the changes (`git add`); never commit unless the operator asked. Deliver the final +report in plain language using only the project's documented terms: +1. Decisions applied — count, one sentence each. +2. Sweep results — the superseded terms searched and the zero-live-hit confirmation. +3. Review verdict per round; what was fixed vs escalated; any fixes applied after the + final round, named as unverified. +4. Exactly ONE next action for the operator — when unverified fixes exist, that action is + the offer of a verification-only extra review round. + +## Success Criteria + +1. Every decision from the conversation appears in the ledger with quoted evidence. +2. `design-doc.md` passes the contradiction sweep — no live statement of any superseded + decision anywhere in it. +3. `implementation_plan_outline.md` was regenerated or fully rewritten — it contains no + correction blocks and passes the sweep and the extraction test. +4. An independent `/rootcause-review` ran on the updated plan; every finding is fixed or + escalated, none ignored. +5. The operator received a plain-language report ending in exactly one next action. diff --git a/internal/cmd/install_skills/perfeval-agent/SKILL.md b/internal/cmd/install_skills/perfeval-agent/SKILL.md new file mode 100644 index 0000000..da70e3e --- /dev/null +++ b/internal/cmd/install_skills/perfeval-agent/SKILL.md @@ -0,0 +1,201 @@ +--- +name: perfeval-agent +description: Evaluate any agentfactory agent's runtime performance from telemetry and session transcripts, walking time down through child agents to the true consumer, and produce ONE evidence-backed highest-impact optimization with verbatim reproduction queries.

Exclude them from all stats. + - `gate-waiting` is NOT queue idle. See `StatusGateWaiting` in + `internal/telemetry/event.go` and its write site in `internal/cmd/done.go`: + a step closed via `af done --phase-complete` records its normal span with this + label instead of `closed`.

Say how many. Never present a + partial population as the whole. +5. **Do not try to read extended-thinking content.** It is persisted zero-length + (timing and count only). The method below recovers what deliberation was *about* + without the text. + +## Phase 0 — Preconditions + +```bash +af telemetry status # expect: telemetry on, endpoints reachable +ROOT=$(git rev-parse --show-toplevel) +FORMULA=$(af agents list --json | jq -r --arg a "$AGENT" '.[] | select(.name==$a) | .formula') +echo "agent=$AGENT formula=$FORMULA root=$ROOT" +``` + +If telemetry is off there is no data; stop and tell the operator.

If the top steps are await/dispatch-shaped (their titles +say "Await…", "Dispatch …"), the time lives in a **child agent**: + +```bash +af agents list --json | jq --arg a "$AGENT" '.[] | select(.name==$a) | .inputs' # child names often appear here +grep -n "sling --agent" "$ROOT/internal/cmd/install_formulas/$FORMULA.formula.toml" +``` + +Re-run Phase 1 on each child that backs a dominant await step, one child at a time, +deepest-first.

No reconciliation, no verdict. + +## Phase 3 — Understand the top step before profiling it + +Read the step's definition in the formula source before interpreting any timing: + +```bash +grep -n -A60 "" "$ROOT/internal/cmd/install_formulas/.formula.toml" +``` + +Know what the step *asks for* (how many discrete actions, what judgment it demands, +what its exit criteria are).
